SEAL -LOCK.

SPECIFICATION forming part of Letters Patent No. 366,241, dated July 12, 1887. Application filed March 26, 1887. Serial No. 232,600. (No model.)

To all whom it 11mg concern:

Be it known that I, EMANUEL OEHRLE, a citizen of the United States,residing at Omaha, in the county of Douglas, State of Nebraska, have invented certain new and useful Improvements in Seal-Locks, of which the following is a specification, reference being had therein to the accompanying drawings.

lhis invention relates to seal locks for freight-car doors; and my object is to provide a seal-lock and latch combined, whereby either functionmay be brought into operation.

The invention consists in certain features hereinafterspecified, and particularly pointed out in the claims.

Referring to thedrawings, Figure 1 represents a car-door and portion of a car provided with a lock constructed in accordance with my invention, the lock being shown in an open position. Fig. 2 is a detail transverse section showing the knife-carrying arm ascending and severing the card or seal. Fig. 3 is a rear view of the latch or knife-carrying arm detached from the loelcplate, and Fig. 4 is a detail in perspective of the knife.

Like letters indicate like parts in all the figures.

A represents the frame-work of a cardoor, and A the door. At a suitable point upon the latter is mounted the lock-plate B, which consists of a semicircular casting having a central perforated boss orhub, B, and radiating arms B and a semi-annular outwardlyflanged rim or guide, B provided with perforated lugs B for the reception of screws, whereby the plate is rigidly attached to the door, and a stop, 13. By the provision of this stop B the pivoted latch G is prevented from falling to such a position as to disengage its arms O with the guiding-flange B. Pivoted to the boss or hub 13 by means of a bolt, 13, is a latch G, the opposite end of which is formed with an engaging-hook, 0, adapted to enter a staple, D, secured'to the frame-work, said hook being perforated at its end for the reception of any ordinary lock or wire having a seal, whereby it is retained against rising. At each side of the latch O are formed laterally-extending inwardly-bent L-shaped arms 0 which enter back of the semicircular flange B of the plate B, whereby the latch may be guided in its radial movement. Upon one of the arms B is formed the seal-receiving plate or pocket E, formed with the side flanges, E E, and the top and bottom flanges, E E, the former being recessed, as at E for a purpose hereinafter referred to, and pro vided with depending pins E. A spring plate, E extends from one side of the plate E midway across the same, the outer edge of which is curved.

Referring more particularly to Fig. 3, a rear view of the latch O, F represents the knifeplate, formed with the opening F, which is preferably provided with a glass, and with the opposite parallel guidingflanges F adapted to fit between and enter the side flanges, 13 E, of the plate E. Below the opening F, and at the center of the plate F, is secured a knife, F consisting in this instance of a securingplate, F perforated for the reception of screws, and having a fixed L-shaped blade,

the bent portion F of which is adapted to eX- tend under the spring-plate E when in the act of cutting or canceling a seal. (See Figs. 2 and 4.)

Having described the construction of my invention, the operation is as follows: A seal the size of the plate E, bearing the name and address of the receiver, is placed within the plate E and under the retaining-pins E, the latch being swung to a position above the plate. The latch is then swung down to engage with the staple D, the knife F, projecting from the latch, passing through the recessed portion E of the flange E, and along down over the seal G (the spring-plate E yielding to the pressure thereof) until it reaches the flange E, by which time it is freed from contact with the seal, whereupon the spring-plate E forces the seal to the front, where it may be inspected. \Vhen the knife passes beyond the edge of the seal, the spring is released and forces the seal sufficiently far to the front to bring it forward of the bent portion of the blade. Thus, should thelatch be lifted sufficiently far to open the door of the car, the knife would be brought into con tact with the edge of the seal and. sever the same.

Having described my invention and its operation, what I claim is 1. In a seal-lock, the combination of alockplate, having a semicircular flanged rim, with a swinging latch pivoted to said plate and provided with arms adapted to take under said flange, substantially as specified.

,2. In a seal-lock, the combination of alockplate, having a seal-plate provided with flanges or guides, and a stop with a pivoted swinging latch carrying a knife and having flanges adapted to pass within said flanges in the seal-plate, substantially as specified.

3. In a seal-lock, the combination of a sealplate, provided with a spring extending partly across the'same, with a latch carrying aknife bent to project back of the spring and seal when in its lowest position, substantially as specified.

4. In a seal-lock, the combination of a semicircular lock-plate having a peripheral flange,

a central perforated boss, and radiating arms, one of which is provided with a seal-plate having guiding-flanges and a flat spring extending partly across the same, with a latch pivoted to said central. boss and provided with a hook at one end, perforated to receive a lock, and with guiding-arms adapted to take under said peripheral flange, and having a knife=plate and guides adapted to be swung down over the seal-plate and take under the seal therein, whereby when raisedthe seal is cut or canceled, substantially as specified.

In testimony whereof I affix my signature,

in presence of two witnesses.

EMANUEL OEHRLE.
